how does a 6 colour or 2 x 4 colour work on a jv3?

[Jamie Wood]

I’ve not seen any prints from a CMYKcm setup, but we are very happy
with the quality we get running 2 x CMYK, and we run a lot of full colour
work. Just bear in mind that you will effectively halve the speed of your
machine should you choose to change. Try running a colour job at 720
or 1440, I’m sure that the quality will be OK.

Cheers,
Jamie

Well I have been in the position of owning a JV-160S (6 colour) and have helped setup a JV3-75SP with (4 colour 2x)

I would say I can see the difference in the print quality with the 6 colour and it is slightly more vibrant, however you could consider that you have 6 carts to worry about when ordering re-fills but when you are on the 4 colour (2x) then you have the two lots of cmyk to worry about, so ordering and stock might be easier on the 4 colour model.

The 4 colour JV3 is infact a fantastic print and I certainly would leave it in that mode, I think it has a better pass formula for putting down ink, also I beleive that one of the heads will actually block up (cannot be sure) as you have 4 heads in the JV3-SP and 3 heads in the JV3-S, the 3 heads are divided into two parts (one colour on the left and another on the right), so if CCMMYYKK is what you got now, then it might CMYKcm00 where the 00s are a head with either white ink or nothing in it. The JV3-S is actually KYCMcm

hope that helps, but I would leave it as it is, the JV3-SP print quality is fab

Only run ours for nearly a month. on 2x cmyk quality is very good, (can only compare with previously bought in prints,)
What size prints are you doing and on what sub-strata ? and what viewing distance?

Jamie, as an aside..
I use signlab, and so there are no profiles for 1440 dpi , Cadlink tell me that 1440 gives unaceptable results on vinyl, so did not include any.

Comments welcome

oh just a quickie… never printed 1440, no profiles and its pointless res… 720 works perfectly (thin or thick)

[Jamie Wood]

I tend to agree that the 1440 setting is a bit pointless, as we get very
good results from 720. However, I have recently installed a 720 x 1440
profile for Avery MPI 2000, and the results are stunning. There is
absolutely no banding whatsoever, even on tricky greens and blues,
where I have experienced banding in the past. The good thing is, we get
virtually the same speed as 720 when using this profile. Using ONYX BTW.

How are you getting on with your JV3 Peter? Do you think you made the right choice?

Cheers,
Jamie.

Jamie,
getting on fine, only gripe is manual is in japanenglish, so had a bit of trial and error stuff, as said print quality, is in my opinion (I am only a novice) very good. Built quality is, apart from a few niggles, also good.
Right decision? Its my first large format printer, so I don’t really have a marker to guage by, time will answer the question though, if I get a good return on my investment, then I will have made the right decision.

just printed my biggest one yet, 1340 x 6m, was a bit like my first kiss, was wondering if it was ok, when I started, but all was perfict…

Our JV3 is the 160s one. The majority of our work is on vinyl. This week I’ve out put 6 swinger sign panels. As I said before we were running at 360 x 720, with this setting you can get a slight banding, but this is only really visable by viewing it at an angle. I think that it is the grain of the print (bi directional).

The reason we’ve been using the lower res is down to matching what we’d been buying in (sort of). Before we bought the JV3 we bought in print from an Arizona which gave a nice pin stripe effect.

I’ll try printing at the best mode this week and see what happens.
